What’s the most interesting Medical Device project you’ve worked on and why?

Wireless Bluetooth LE Pulse Oximeter. The electrical design required close coordination and iteration with Tensentric’s industrial design team to successfully miniaturize the electronics to fit in such a tiny form-factor.

What do you like about working at Tensentric?

Being able to do a little bit of everything from hardware design to software and mechanical design. I enjoy working with other Tensentric engineers that have such a wide variety of multi-disciplinary knowledge and interests.

What unique set of skills do you bring to Tensentric?

I’ve done a little bit of everything, EE, ME, SW and can see other people’s viewpoint. I have an ability to bridge disciplines.
